  • NOT Cal KIng
    Verified Purchase

    I purchased this 9 months ago, it sleeps fair. I would not rate this as plush, more as firm. The sizing is totally incorrect. I have a Cal King platform bed and there are several inches at the foot of the bed. Overstock states that the is 84 inches, I measured it at just under 80 inches. The width is just under 70 inches. I got a good deal, but it wasn't worth it:-(

  • Sagging and collapsed after less than one month.
    Verified Purchase

    This was shipped to me and was delivered in thin plastic only. I am the only one sleeping on it 130lbs. It began to sag after two nights! Now, after less than a month, it's collapsed on the side, like an accordion!!! What a laugh! I've have never seen this before, even with $50 childhood mattresses. Now, I have to do the Serta warranty. They are charging me $35 to come out and "inspect" it and will "determine" if it's defective or not and will select a "comparable" set if one is available. I don't know what that means, but I'm filing on Serta and Overstock with the BBB if they don't have a new, good mattress in my home in the next two weeks. Period.

  • Very comfortable bed!
    Verified Purchase

    I bought this bed for my son who has lived with chronic lower back pain for years. He is a truck driver and couldn't remember the last time he slept through the night. He tried memory foam but it didn't work either. The first night on this bed, he slept like a baby and his wife told me that he never tossed and turned once. He loves this bed and his sleep has improved 100%.
